Floods, exacerbated by escalating urbanization, pose significant threats to life and property globally. Over the past decade, the Esenyurt district in Istanbul has witnessed a series of floods, highlighting existing flood risks. Rapid population growth in this area and dense urbanization caused by intensive construction increase flood risks. Given these factors, the study focuses on examining the historical impact of urbanization on flood risks, considering spatial and temporal changes. Landsat-8 satellite data, specifically examining NDVI, NDBI, and BU, was employed to detect building imprints and reveal their historical backgrounds for temporal risk calculations. The analysis showed a sudden increase in urbanization rates in 2016, 2017, and 2021. In the flood risk calculations, 2014 data for a return period of 100 years were used and flood inundation depth, economic damages, affected population and depth-damage function were taken into consideration. The results indicate that from 2014 to 2022, increasing urbanization led to a 32.9% increase in the population affected by floods, a 22.3% rise in potential economic damage, and a 13.6% increase in total flood risk. The relationship between flood risks, contemporary urbanization, and its economic dimensions has been evaluated to reduce risks and achieve sustainable cities.

The outbreak of COVID-19 and its consequences have altered people's perceptions of the availability of high-quality housing. Nigeria, the most populous country in sub-Saharan Africa, has taken many initiatives to address its growing population's housing demands. However, considerable focus has been placed only on housing quantity at the expense of housing quality. This study aims to investigate the interplay of factors affecting the provision of high-quality public housing projects in Nigeria. The objective is to identify the factors that significantly influence project success and failure in the delivery of quality public housing projects. A descriptive survey design with 351 randomly selected households and built environment experts (BEPs) was used. A self-developed structured questionnaire was used to collect data from households, buildings, and professionals over the course of three months. The findings indicate that in several buildings, the indoor air temperature and relative humidity extend acceptable limits (for example, 28 °C and 70% RH), which can have an effect on indoor air quality. Meanwhile, responses from the BEPs revealed that in order to develop high-quality housing, adequate project financing, evaluation of suitable building materials, and project management expertise were required. The study's conclusion emphasises that considering only the number of houses required to accommodate Nigeria's growing urban population is insufficient; rather, other factors such as appropriate design for improved air quality, high-quality and appropriate building materials, adequate project financing, and project management expertise would result in the quality delivery of livable public housing in Nigeria.
COVID-19 的爆发及其后果改变了人们对高质量住房供应的看法。尼日利亚作为撒哈拉以南非洲人口最多的国家，已经采取了许多措施来满足日益增长的人口住房需求。然而，相当多的人只关注住房数量，而忽视了住房质量。本研究旨在调查影响尼日利亚提供高质量公共住房项目的各种因素的相互作用。目的是确定在提供优质公共住房项目过程中对项目成败产生重大影响的因素。研究采用了描述性调查设计，随机抽取了 351 户家庭和建筑环境专家（BEPs）。在为期三个月的时间里，使用了一份自行开发的结构化问卷，从住户、建筑和专业人员那里收集数据。调查结果表明，一些建筑物的室内空气温度和相对湿度超出了可接受的范围（例如 28 °C 和 70% 相对湿度），这可能会对室内空气质量产生影响。同时，从建筑设计单位的反馈中发现，要开发高质量的住房，需要充足的项目资金、评估合适的建筑材料和项目管理专业知识。该研究的结论强调，仅仅考虑满足尼日利亚不断增长的城市人口所需的住房数量是不够的；相反，其他因素，如改善空气质量的适当设计、高质量和适当的建筑材料、充足的项目资金和项目管理专业知识，将有助于在尼日利亚提供高质量的宜居公共住房。

This study examines the dynamics of Urban Land Use Succession (ULUS) in Upper Hill, Nairobi, highlighting the impact of neoliberal policies and private sector-led urban redevelopment. It investigates how land tenure, public infrastructure, and planning controls shape urban landscapes, leading to patchwork land use patterns and environmental misalignments. The case of Upper Hill, transitioning from a serene residential area to a bustling commercial hub, is explored to understand the determinants of ULUS and propose strategies for streamlined urban development. Employing Neoliberal Theory and hypothesis testing, the research identifies spatial policy as the primary driver of ULUS. The study suggests innovative approaches, including land assembly and the establishment of an Urban Redevelopment Authority, to harmonize urban development. These strategies aim to bridge the gap between private and public land development, ensuring coherent urban growth. The research contributes to the understanding of urban redevelopment, particularly in Kenyan contexts, by offering a model that integrates public and private interests. This model serves as a blueprint for managing urban transformation in Nairobi and other similar urban settings, promoting sustainable and equitable urban development.

This study investigates the influence of urban green landscapes on the Quality of Life (QoL) in Kaduna Metropolis, Nigeria, focusing on residents' perceptions and sustainable urban development strategies. Conducted from May to July 2023, the quantitative research surveyed 377 residents using a questionnaire. Statistical analysis, including correlation and t-tests, was performed using SPSS version 23. Findings reveal a positive perception of urban green spaces, significantly contributing to residents' QoL. Key results include high satisfaction with green areas enhancing environmental beauty (Mean=4.88, SD=0.90) and providing recreational appeal (Mean=4.45, SD=0.95). Additionally, these areas significantly impact perceived value (Mean=4.78, SD=0.93), prestige (Mean=4.92, SD=8.18), and attachment to the environment (Mean=4.71, SD=0.831). Residents with accessible and functional green spaces express higher satisfaction levels (Cronbach’s Alpha > 0.9). The study underscores the importance of urban greenery in improving urban living conditions and offers strategic recommendations for sustainable urban planning. Addressing a gap in literature, this research provides empirical insights into residents' perspectives within Kaduna Metropolis, contributing to academic discourse and practical urban development approaches.

This study investigates liveability in the context of sustainable public housing in Niger State, Nigeria, where existing housing efforts have fallen short of residents' satisfaction. Recognizing the critical link between liveability indicators and environmental sustainability, this research aims to identify key liveability variables that could be integrated into the design and construction of sustainable public housing. Employing a mixed-method approach, the study involved cluster sampling for selecting housing estates and units, followed by the administration of 910 questionnaires containing 102 questions on liveability variables. Analytical techniques, including Hierarchical Cluster Analysis, Factor Analysis, and Multiple Regression Analysis, were used to group, refine, and validate the liveability variables. The results revealed 21 significant variables that collectively could achieve a 92.9% satisfaction rate among residents if incorporated into public housing design. These findings underline the potential of addressing liveability in the pursuit of sustainable housing solutions, offering insights for urban planners, architects, and policymakers. By focusing on the residents' perspectives, the study contributes to a more user-centred approach in public housing development, promoting long-term satisfaction and reducing the need for post-occupancy alterations.

This article explores the connection between Smart Growth and the decolonization of urban growth management in Egypt, examining the impact of former colonial influence on present urban policy and practices. Drawing insights from the urbanization of Egyptian desert areas before and after the New Urban Communities Program (NUCP), it scrutinizes how historical influences adversely affect contemporary approaches, inducing socio-economic impacts. The primary objective is to identify the root causes of misguided urban growth management practices, arguing that mono-institutional and sectoral development is rooted in Egypt's quasi-colonial history preceding the NUCP. The research employs a comprehensive methodological approach, using descriptive qualitative methods to investigate the growth of emerging cities based on Smart Growth principles and quantitative analysis to assess population decongestion resulting from the NUCP. It evaluates the implementation of Smart Growth principles during the NUCP and pre-NUCP, offering insights into adverse management practices. Despite the NUCP's goal to alleviate congestion, only 1.6 percent of the population was decongested by 2017. The research highlights the need for a new municipally guided growth model, emphasizing indigenous and locally validated approaches. This model aims to rectify inefficiencies in current urban management practices, fostering a responsive and sustainable approach aligned with local community needs.

In light of the rapid global urbanization, urban design has been shown to contribute largely to promoting the health and well-being of urban citizens. However, studies of urban design are underrepresented in low- and middle-income countries in Asia, where urban forms are traditionally compact and complex with multiple layers. Hanoi, a typical city in low- and middle-income countries, exhibits five unique urban typologies generated through official planning, unregulated development, and historical fluctuations. This study examines the perceived urban design from a sample of 218 participants across five urban typologies in Hanoi using an established scale. The findings suggest that perceived urban design is significantly influenced by urban typologies. Old urban typologies tend to report higher scores of land use mix and access to services but lower scores of walking facilities and street connectivity than modern urban typologies. The study contributes to our understanding of urban design in Hanoi, providing policymakers and urban designers with essential insights for sustainable urban development.

In the city of Messina, the multiplicity of vulnerable situations is a distinctive feature and is representative of the pervasiveness of the risk conditions present in the Italian territory. The critical residential tissues are part of an extended geography in which, to the conditions of seismic and hydro geomorphological vulnerability, are added additional criticalities including altered natural resources, abandoned infrastructure, brownfields, quarries, and unregulated landfills, etc. Despite this, for Messina, there is still no urban planning tool capable of interpreting in an integrated way the risks present, which instead continue to be addressed on an emergency basis and individually, without considering the interactions that are generated and of further damage. For these reasons, Messina was chosen as a prototypical case study, at the national level, to start an experimentation aimed at developing an urban planning tool capable of a new integrated approach to risk interpretation and management. In this process, a decisive role was aimed at building an updated knowledge of the territory through the identification of widespread critical conditions using multiple GIS tools and thanks to the interaction of some analytical-specialist readings from different sources. The results of this process are represented in a system of maps that are strongly integrated with each other and constitute a working document for the interdisciplinary group drafting the General Urban Plan.

The shopping mall has emerged as an important component of many cities. While the rapid development of malls and the increasing patronage show their viability and acceptance by the populace, respectively, there is a dearth of studies that examine the impact of its physical and behavioural attributes on attachment. This study examines the effect of physical characteristics, activities, and socioeconomic characteristics on place attachment to the first standalone mall in Ibadan, Nigeria. From a sampling frame of 7, 115 shoppers, quantitative data was obtained from 350 respondents using systematic sampling on April 29, 2017, through a structured questionnaire. The data was analysed using mean, factor analysis, cross-tabulation, correlation, and categorical regression. The findings show that the most prevalent activities are meeting others (α = 0.77); leisure (α = 0.75); and, parties and hanging out (α = 0.70). The important physical attributes are circulation, wayfinding, and aesthetics (α = 0.87); access to mechanical conveyors, mall decoration, and quality materials (α = 0.80); and, ambience (α =0.79). However, the regression results show that the most important factors of attachment are access to mechanical conveyors, mall decoration, and quality materials (β = 0.334); leisure (β = 0.279); purchasing activities (β = 0.236); and, meeting others (β = 0.165). Hence, these factors should be considered in creating new malls in the city. In the context of urbanism, this is key to the social and economic revitalization of cities.

However, the regression results show that the most important factors of attachment are access to mechanical conveyors, mall decoration, and quality materials (β = 0.334); leisure (β = 0.279); purchasing activities (β = 0.236); and, meeting others (β = 0.165). Hence, these factors should be considered in creating new malls in the city. In the context of urbanism, this is key to the social and economic revitalization of cities.","PeriodicalId":34438,"journal":{"name":"Journal of Contemporary Urban Affairs","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139209577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Recently, urban regions are experiencing prolonged heat exposure due to climate change and increased population expansion. Physiological, psychological and behavioural measures improve residents’ thermal comfort to solve the overheating issues generated by the scenario. However, adaptive strategies have not been clearly categorized based on the building construction process. This paper systematically reviews 101 documents published from 2013 to 2023, across 22 countries, with a focus on Nigeria. Using descriptive statistics and content analysis, we identify and categorize 52 adaptive strategies into four groups: urban design, effective building design, insulation, and occupants’ behaviour. These strategies are further classified according to their application in the building process stages: pre-design, design, construction, and post-construction. The study provides a full response to overheating in the building sector with efforts to reduce energy consumption rate and greenhouse gas emissions. The findings of the study contribute, significantly to improvement in occupants’ health care and well-being, as well as high productivity levels and socioeconomic benefits. Future research is therefore recommended in the efficiency of its implementation to develop innovative and cost-effective solutions in the construction industry towards sustainable urban development.
